why didn't i get the emergency alert

There are several common reasons why an emergency alert might not have been received:

1. The phone might be off, in flight (airplane) mode, or out of cellular coverage, which prevents the alert from reaching the device.
2. The phone might not be capable of receiving emergency alerts, either because it is an older model or its software is not up to date.
3. The alert system targets specific geographic areas, so if the phone was outside of the targeted area, it would not receive the alert.
4. The phone may be connected to an older network (e.g., 2G or 3G) which may not support the alert system.
5. Emergency alerts do not require mobile data or Wi-Fi but do require cellular signal reception.

Also, some phones may have settings related to emergency alerts that could affect receiving them, and it’s important that these devices have the latest software updates installed. In summary, not receiving an emergency alert is often due to factors like phone status, network capability, location, or phone compatibility and settings.
